I spent a while drawing a texture in Texture paint mode, and all was OK. It was rendering fine for a while, but now, it’s gone. I’m back to my old material again, even though the UV texture I used to paint the image onto is still assigned to my plane.
This has happened a couple of times now and it takes me ages to redraw the texture. I was wondering if I’ve just inadvertently switched it off with some keystroke, or has it really gone?
